In order to reduce trailing phenomenon for moving image in FPD (Flat Panel Display)  Then  Finally  grayscale control algorithm is proposed that simulates CRT (Cathode Ray Tube) grayscale rendition process. First  based on algorithm derivation  implemented main program with VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) is presented and specific rendition process is described. Experimental results indicate image quality is evidently improved and proposed algorithm reduces trailing phenomenon nearly 90%  after the reason of trailing phenomenon for moving image is introduced  algorithm realization steps and compared experiment results of traditional and proposed FPD grayscale control algorithm are discussed  when FPD displays moving image  work processes of human eyes are illuminated and grayscale rendition of a pixel is obtained  according with eyes reflection mechanism and programs can correctly implement on circuit board. 2010 IEEE.  when seeing moving image on CRT and FPD

STIM (Solar Total Irradiance Monitor) can be used on sun-synchronous polar orbit weather satellites to measure the total solar irradiance. It contains three independent and identical wide view absolute radiometers. They are mounted on the satellite in an angle which ensure the sun scan over the field of view of the absolute radiometers. This measurement method doesn't need the instrument tracking the sun but the sun scan over the field of view of the absolute radiometers in each orbit cycle. The paper presents the measurement method of simulation for solar irradiance measurement and calibration by mounting the instrument on a two-axis rotation table. By controlling the rotation angle velocity of the instrument in the meridian direction being the same as that of the weather satellite's on orbit  we can measure the solar irradiance when the sun scan over the field of view of the absolute radiometers to simulate the onboard state. And we have operated the measurement with the prototype of STIM. The SIAR-1 is traceable to WRR and serves as a transfer standard. So simultaneous comparison measurements between SIAR-1 and each of the three wide view absolute radiometers are measured to provide calibration corrections to the instrument. And we have a further study at the influence of stray light to the measurement results. This paper presents the method of simulation experiment and calibration for solar irradiance measurement with Solar Total Irradiance Monitor on board.
